Objective: To analyze the clinical and genetic characteristics of a 46,XX case of testicular disease with prostate germ cell tumor and explore its pathogenesis.
Methods: The clinical features and pathological examination of the patient were reviewed, and the genetic basis was analyzed by chromosome karyotyping analysis and fluorescence in situ hybridization.
Results: The patient had slightly short stature, small testicles and large breast. Serum alpha fetoprotein was significantly increased, along with increased follicle stimulating hormone, luteinizing hormone and prolactine, and lower level of testosterone. The karyotype was 46,XX. Fluorescence in situ hybridization has identified the presence of SRY gene at the end of short arm of one X chromosome. The pathological diagnosis was primary germ cell tumor of prostate, mainly of yolk sac tumor type.
Conclusion: A rare case of 46,XX testicular disorder of sex development combined with germ cell tumor of the prostate was diagnosed, which has enriched the phenotype spectrum of the disease and provided clues for the treatment of the disease.

Background: The establishment of kinetochore-microtubule attachment is essential for error-free chromosome alignment and segregation during cell division. Defects in chromosome alignment result in chromosome instability, birth defects, and infertility. Kinesin-7 CENP-E mediates kinetochore-microtubule capture, chromosome alignment, and spindle assembly checkpoint in somatic cells, however, mechanisms of CENP-E in germ cells remain poorly understood.

The evolution of green plants from aquatic to terrestrial environments is thought to have been facilitated by the acquisition of gametangia, specialized multicellular organs housing gametes. Antheridia and archegonia, responsible for producing and protecting sperm and egg cells, undergo formative cell divisions to produce a cell to differentiate into germ cell lineages and the other cell to give rise to surrounding structures. However, the genes governing this process remain unidentified.

Basal ganglia germinomas are uncommon neoplasms. Basal ganglia germinomas exhibit high sensitivity to both radiation therapy and chemotherapy. In contrast, surgery is the standard treatment for most primary brain tumors (such as gliomas, which are the most common tumors in the pediatric basal ganglia region).

Background: Local hen layers play a crucial role in egg production and the poultry industry. Optimizing their performance, egg quality, and overall health is of paramount importance.
Aim: This research aims to examine the effects of different feed forms on gut bacteria and subsequent effects on productivity, egg quality, and intestinal morphology in indigenous laying hens.

Background: Techniques for sperm cryopreservation have exhibited their potential in male fertility preservation. The use of frozen-thawed sperm in fertilization (IVF) cycles is widespread today. However, many studies reported that cryopreservation might have adverse effects on sperm DNA integrity, motility, and fertilization, probably due to cold shock, intra- and extracellular ice crystals, and excess reactive oxygen species (ROS).
